SP: 'Getting back to the original question about teleportation experiments, are you saying that it would be impossible, or just technically very difficult to preserve personal identity whilst undergoing such a process? As Brent pointed out, technical difficulty is not an issue in thought experiments. ,

MP: I have answered this, in responding to Brent. In summary I say: if it is just A [any old] rendition of a human you want, then given that thought experiments allow that all practical challenges can be overcome, the answer is Yes! On the other hand if the strict requirement of an exact copy of a particular person is required to be output then it becomes a question of whether or not truly infinite computing power is required to calculate the changes occurring within the original at scan time. If it is then the answer is NO, because infinity is infinity.

But *your* infinity is just *really big*.  There are only a finite number of 
atoms in a person and they have only a finite number of relations.  So how can 
an exact copy require infinite resources?
